Why D.A.I. Scientific

  • Does It Matter Where You Buy Your Lab Equipment?
    Not all lab equipment suppliers are created equal. Here is why you should get a quote from D.A.I. Scientific:
  • Competitive Prices
    Since we directly represent the manufacturer, you get the best price available — unlike a distributor who buys the product and then marks up the price to you. We have long term relationships with these manufacturers that provide not only a great price but superior equipment packages.
  • Providing the Right Recommendations
    We work with a lot of lab equipment consultants and architecture and engineering firms to provide recommendations for new buildings or renovations. But we’re your resource no matter what. Companies continually call us for ideas and recommendations on equipment purchases even after a project is finished, and we’re happy to help.
  • 50+ Years of Experience
    We’ve sold thousands of pieces of lab equipment, which means we know how to avoid common challenges and pitfalls that can occur during a purchase. If you need help with purchasing a single piece of equipment, or an entire lab for a new building, let our experience save you time, money and unnecessary headaches.
  • No Surprise Fees
    We believe in complete transparency, which means we won’t surprise you with any fees during the process. We’re up front about our pricing, and our goal is to help you understand the complete cost from order and delivery to setup and training.
  • Training
    Our experienced, factory-trained representatives have the specialized knowledge to answer your questions and help you pick out exactly what you need. They can also help you set up your equipment, provide training for you and your lab technicians and answer questions over the lifespan of your product.
  • One-Source Provider
    We have a long history of working with market-leading manufacturers, and customer service is our top priority. Whether you need a single replacement unit for your lab or an entire equipment package, D.A.I. Scientific is your one-source provider for all your laboratory equipment needs.
